The different flavors of Stata

 

Stata/MPThe fastest and largest version of Stata. Now in addition to its multiprocessing capabilities, Stata/MP can also analyze more data than any other flavor of Stata. Stata/MP can analyze 10 to 20 billion observations given the current largest computers, and is ready to analyze up to 281 trillion observations once computer hardware catches up.

Stata/SE: Stata for large datasets

Stata/IC: Stata for mid-sized datasets with up to 2048 variables

 

 

Detailed feature description

Most computers purchased since mid 2006 can take advantage of the advanced multiprocessing of Stata/MP. On dual-core chips, Stata/MP runs 40% faster overall and 72% faster where it matters, on the time-consuming estimation commands. With more than two cores or processors, Stata/MP is even faster. Stata/SE, Stata/IC, and Small Stata differ only in the dataset size that each can analyze.

Stata/SE and Stata/MP can fit models with more independent variables than Stata/IC (up to 10,998).

Stata/IC allows datasets with as many as 2,048 variables, and the maximum number of observations is 2.14 billion. Stata/IC can have at most 798 right-hand-side variables in a model.

All the above flavors have the same complete set of commands and features and include PDF documentation.

Multicore performance

MP licenses can be used on both 32 - and 64-bit computers, but they only go faster if your computer has at keast the same number of processors as your license, i.e., MP2 will work more efficiently than a SE only if the computer has at least 2 processors. As you can see from the following graph, a Stata/MP is considerably faster than a Stata/SE.
